This development library isn't strictly Wiibrew, but it's a mighty useful tool that homebrew developers for other platforms out there might enjoy. WiiRemoteJ is a library that allows your computer to interact with the Wiimote through Bluetooth, with Java as the medium. Here's the changelog since the original release:

7/03/08 - v1.4
-Fixed bugs with multiple remotes
-Made Exceptions thrown when connecting via findRemote() propagate to user
-Added Balance Board support
-Updated README and LICENSE appropriately

2/24/08 - v1.3
-Improved thread cleanup after disconnect.
-Added ability to create "fake" WiiRemotes for use in initializing events
-Updated README and LICENSE

1/14/08 - v1.2
-Workaround for BlueSoleil bug added.
-GuitarExtension added

12/26/07 - v1.1
-Numerous bug fixes. I've forgotten what they all are.
-Added support for systems that don't have mice.

6/25/07 - v1.0
-Totally redid ButtonMaps to allow multiple types of actions (key presses, mouse
clicks, and mouse scrolls) to coexist.
-ButtonMap subclasses still exist, but now serve only to provide convenience
constructors. They have no additional or specialized functionality.
-ButtonMaps can also now require buttons to be pressed on both the remote and a
peripheral to trigger.
-Added isAnyPressed and isOnlyPressed as button evaluation methods.
-By default, no lights turn on when the remote is connected (all four lights used to turn
on). You should turn on at least one light so that users know the remote is on.
-Got my hands on and tested a classic controller. There were bugs. They are fixed.
-Changed left and right triggers on the classic controller to percents instead of values.
-Fixed a lot of bugs.
-Improved IRAccelerometerMouse to be more reliable when the mouse is being
moved around (there is some acceleration). It's not where I want it yet, but it's better.

4/19/07 - v0.9
-Fixed a memory leak with WRButtonEvents
-Fixed/clarified some documentation
-Added mouse-wheel button mapping support
-Fixed bug where button mapping could cause keys to "stick"
-Improved efficiency of button mapping in general
-Many changes to the test/sample file WRLImpl.java (to demo scrolling)

4/03/07 - v0.8
-Initial release!
